Precautions on Replenishing Compressor Oil

Precautions on Replenishing Compressor Oil

When replacing air conditioning parts with new ones, it is necessary to replenish A/C system with oil by the amount supposedly lost with removed parts.

When Charging Refrigerant Only

When charging A/C system with refrigerant without replacing any component, replenish with the same amount of measured oil when recovering refrigerant (if not measure, replenish with 20 cm3 (20 cc) oil).

When Replacing Compressor

NOTE:

Use of a compressor oil other than the specified oil is inappropriate for the components of the A/C system and may cause problems with operation of the system.

Use only the specified compressor oil or equivalent.

Compressor oil is sealed in each new compressor (1) by the amount required for air conditioner cycle. Therefore, when using a new compressor for replacement, drain oil from it by the amount calculated as follows.

"C" = "A" - "B"

"C": Amount of oil to be drained

"A": Amount of oil sealed in a new compressor

"B": Amount of oil remaining in removed compressor

NOTE:

Compressor assembly supplied from factory is filled up with the following amount of oil.

Compressor oil: 99000-99088-00E (Compressor oil (DH-PS, 250 cc))

Amount of oil in new compressor
150 (±10) cm3 (150 (±10) cc)

Amount of compressor oil to be replenished after part replacement
Evaporator: 50 cm3 (50 cc)
Condenser: 30 cm3 (30 cc)
Receiver/dryer: 10 cm3 (10 cc)
Hoses: 10 cm3 (10 cc)
Pipes: 10 cm3 (10 cc)
